If the engine is pushed towards the redline two things happen, more windage and churning of the oil in the crankcase, this produces heat and more oil being pumped to the top of the motor, less in the sump so a small quantitiy of oil being pumped through the engine over and over. This cause the oil to gain heat. There can be as much as 3 quarts of oil not in the pan due to this at high RPM under some conditions. So at 6000 rpm you might have ok temps but at over 7000 no.

Thats why guys that are autocrossing in short spurt are seeing high oil temps.

I suspected that we could use more oil in the sump given the other heating concerns. I was bit surprised to learn how little oil the 370Z takes as I was expecting at least six (6) quarts. My belief is that both a larger sump and an oil cooler make this engine a better setup.

With my cooler I'm up to 6 qts. A deep sump or pan extension would bring that to 7. I just found these low profile scoops on my shelf from an aborted past project.....Low enough profile they might work well modified and mounted to the Lower tray to ventilate the sump...Hmmm....

CAI project in the rear..Stay tuned on that!

We have found in doing TIme Attacks with the 350Z that a larger sump, pan baffles, big oil cooler and an Accusump was needed to keep the engine alive with serious suspension, aero and sticky tires.

Every bit helps.
